Webserver working for full website with LMP.

This version of code still does not work for UMP,
and also it does not work for httperf test.

Also, there is lot of commented out code which was helpful for me
in debugging the issue of randome page-fault.

Webserver working for small websites

Partially working version of the modified network stack.
Status: Networking works
Small website test works (Barrelfish website without pdfs)
Full website test does not work (Barrelfish website with pdfs)
Tests done with e1000n running on separate core

this version of code works when application and driver are on different
cores. Which means, when they are using UMP it works, but not when they are
using LMP

Added code to efx_nic_create and everything related/dependent

Fixed the webserver freezing problem by using nonblocking event dispatch

commented out webserver benchmarking code

Factored out some more code from ethersrv.c into ethersrv_support.*

Moved the network benchmarking code from lwip/init.* into contmng/netbench.*
Still to move the code from the driver part ethersrv.c

Fixed the problem of random retransmits happening in send path.
The problem was in the way tx_notify was handled and the assumption that
hardware might return notification out-of-order.

Many changes to get the udp_throughput test working
Currently it pushes network upto 92M (compared to Linux 117M)
But there are still couple of issues
1. For large number of pkts (320000), few pkts (631) just disappear
2. The feedback given when there is packet drop is not yet used
by lwip

Merge from ASPLOS tree.

Initial version of public stable barrelfish repository.
